X: Rebirth Goes 64-Bit

The EGOSOFT
Forums have details on a new version 2.20 patch that's now live in X:
Rebirth, which in addition to fixes and improvements for the space-shooter
reboot, also makes the 64-bit executable the default (thanks
IncGamers). Here's word on the change that explains that continued 32-bit
support will not be indefinite:

We are now sufficiently confident about
the 64-bit version of the game to make this the default. Both 64-bit and 32-bit
versions now include this information in the game's start menu. If you encounter
serious problems with 64-bit and would like to try reverting to 32-bit then you
can subscribe to the 32-bit "beta" using the Steam client. To start using the
32-bit version. right-click X Rebirth in the Steam client, select Properties and
go to the Betas tab then select release_32 from the dropdown list. If you are
running a 32-bit version of Windows you will automatically receive the 32-bit
version of the game, though such Windows versions remain unsupported.

Note: The system requirements for the game have always stated that it requires a
64-bit version of Windows, and that future updates for the 32-bit version are
not guaranteed indefinitely.

We suggest that if you create a savegame in 64-bit you use that savegame with
subsequent 64-bit-versions only and do not load it into a 32-bit version. While
we do not know of any issues in practice with savegames between the two
versions, there is a theoretical possibility that you might corrupt your
savegame to a point where it cannot be restored if you load a 64-bit savegame
into a 32-bit version.
